configuration file for .net services application failing to copy?

[judd williams]

have a script(powershell) task running.

details are:
deploy/deploy-web.ps1
-------------------------
-webserver "${bamboo.WebServerName}" -projectname "monitoring.web" -artifactdirectory "${bamboo.build.working.directory}\web"

below you can see files are copied ... skip ahead to copy.   
the appsettings.rsdev.json doesn't get copied... or to be clear.. the file doesn't contain the conents of rsdev.  its contents are the original file's contents.

any thoughts why?  

also, is there documentation how/why this happens?  is it automatic?  I do want this behavior but assuming its default as I don't have any tasks to trigger this copy.  Please advise.
